Cost estimation for facilities depends on early concept selection and critical inputs, often complicated by uncertainty in one or more of the critical inputs. Empirical cost models and cost modeling methods using these inputs vary in degrees of scope, comprehensiveness, and robustness.

The recycling of produced water and fracture flowback water for reuse in hydraulic fracturing is on the rise in the development of unconventional resource plays.

This paper presents results from an ongoing research project (SINTEF 2011) on pressure-tolerant power electronics. The main goal of the research is to provide and demonstrate solutions that enable power-electronic converters to operate in pressurized environments.

Operators are increasingly recognizing the need for a systematic assessment and management of flexible pipe integrity, but the identification of critical criteria and the means to best achieve valid and efficient inspection and monitoring (I&M) continues to evolve.

Final commissioning and initial startup was the source of lively discussion at a recent applied technology workshop held in New Orleans. A summary of key points is provided.

The selection criteria for multiphase boosting options remain somewhat subjective. A comprehensive literature review into the working principles of the major pump types identified the intrinsic advantages and limitations of each technology for subsea and downhole applications.

Engineers in the oil and gas industry make tough decisions for a wide variety of issues, including risk and safety, and about design and other types of tradeoffs, as well as operational assessments.

Produced water and its treatment and management are growing challenges in all producing regions.

Investments in floating production systems are expected to increase sharply over the next five years, driven by a surge in installations.
